Selection Types

The application allows for two selection types:
• Selection for manipulation. Selected fragments of the structure are highlighted in green. This is a default selection type.
• Selection for analysis.

Selection for manipulation

When this selection type is activated, selected fragments of the structure are highlighted in green.

The following manipulations are available:
• Varying loop radii. Select a loop. Hold down the Shift key and move the mouse cursor down to increase the radius of the loop or up to decrease the radius of the loop.
• Moving a helix around the loops. Select a loop. Use the mouse to select a helix, hold down the key and move the mouse cursor up to move the helix clockwise relative to the loop or down to move the helix counterclockwise relative to the loop.

NOTE.
Ensure that there is enough spacing on the arc between two helices before using this action. To increase spacing, increase the radius of the loop.

Selection for analysis.

When this selection type is activated, selected fragments of the structure are highlighted in yellow. Choose the button the activate this selection type.

When the toolbar button is switched on, the following buttons become available:
- Objects Selection mode. Enables the mode to select a helix or a loop by clicking the nucleotide that the helix or the loop contains.
- And selection mode - In this mode, each subsequent selection unselects the previously selected item.
- OR selection mode - In this mode, all subsequent selections are added to the previously selected items.
- XOR selection mode - In this mode, a previously selected item is unselected by subsequent selection.

Click the toolbar button to invert a selection. Click the toolbar button to select all elements in the model. Click the toolbar button to unselect all elements of the model.

NOTE.
The selection made for analysis is automatically displayed in the "Structure view" panel.
